At the risk of being a pain, can I re-open this thread?
Until recently the starter on my '33 AH tourer has always performed as it should. Until when I last took the car out on a local run just a few weeks ago, it started perfectly well. Post-lunch, it merely gently whirred and whizzed (simulating a jammed starter noise) but, it was not engaging. Fortunately the car started immediately on the handle.
Removed it for inspection and nothing apparently wrong - as far as I could tell. Brushes with plenty of meat on and well bedded in, commutator clean and bright, no debris or junk inside. Same symptoms when tested OFF the car, on the same battery (so no thoughts of dodgy earth connection), but still no satisfying 'clunk' as I would expect when it should 'throw out' and engage. Tried my spare (same good condition as the other) and same whirring/whizzing noise and the same languid spinning - once again all on the same battery...
Must therefore be battery I thought, but it registers about 6.1v (off load) and seems only to drop only about 0.5v when starter pulled.
Despite that reading, it MUST be battery, right? BTW my meter is a small - but modern - device which I think is accurate.
What have I missed?
Be grateful for any ideas, suggestions or thoughts.
Thanks in anticipation.
